Bad Debt - Savannah Martin Mysteries , #14

When every member of a rural Sweetwater family is murdered in their beds, Maury County sheriff Bob Satterfield calls on the Tennessee Bureau of Investigation for help. While Savannah's husband, TBI agent Rafe Collier, heads to their shared hometown to help the sheriff figure out who and what is behind the grisly massacre, Savannah goes along to assist her old friend Yvonne McCoy's quest to gain ownership of Beulah's Meat'n Three restaurant. But when Beulah Odom's death turns out to have been murder, suddenly Yvonne's on the hot seat.
And with the sheriff occupied elsewhere and Beulah's family gunning for Yvonne, it's up to Savannah to figure out the truth before her old friend lands in jail... or six feet under.
